Embodiment Construction

[0034] In order to make the object, technical solution and advantages of the present invention clearer, the embodiments disclosed in the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0035] One of the core ideas of the present invention is to provide an autonomous dormancy and wake-up system for star vehicles. By detecting the current of the solar battery, the highest battery capacity of the battery can be determined throughout the day, and it can be judged according to the highest battery capacity of the battery throughout the day whether the energy consumption demand of the overheated night is met. If If not satisfied, control the rover to sleep; design a wake-up circuit, which is composed of a solar battery, a power supply relay, a normal power supply circuit of the MPPT circuit, and a wake-up circuit. When the rover is working normally, the solar battery generates power for the load of the rover through the MPPT ...

Abstract

The invention discloses an autonomous dormancy and wake-up system for a Mars rover. The autonomous dormancy and wake-up system comprises a solar cell, a power supply relay, an MPPT circuit, a wake-up relay, a temperature relay, a wake-up relay coil, a wake-up resistor, a Mars rover load and a PCU power supply, wherein the solar cell is connected with a common end of the power supply relay; the PCU power supply, the wake-up relay coil and the wake-up resistor are arranged in parallel to form a wake-up circuit; the PCU power supply is connected in series with the wake-up relay and then connected to a B end of the power supply relay; one end of the wake-up relay coil is grounded after being connected in series with the temperature relay, and the other end is connected to the B end of the power supply relay; one end of the wake-up resistor is grounded, and the other end is connected to the B end of the power supply relay; the Mars rover load and the MPPT circuit are connected in series and then connected to an A end of the power supply relay to form a normal power supply circuit. According to the dormancy and wake-up system, autonomous dormancy and wake-up of the Mars rover are realized, so adaptive Mars weather environment and communication constraints are formed.

Description

technical field [0001] The invention belongs to the technical field of on-orbit autonomous operation control of spacecraft, and in particular relates to an autonomous sleep and wake-up system for a Mars rover. Background technique [0002] Similar to Earth, Mars has seasonal changes and climate changes, which have an impact on the power generation of the rover's solar cells and are uncertain. Since our country's Mars rovers do not use nuclear batteries, it is not ruled out that solar cells will generate insufficient power and an energy crisis will occur during the work on the fire surface of the Mars rover. In addition, due to the limited communication between the ground and the fire, the Mars rover communicates with the ground only once on each Martian day. The ground may not be able to know the energy balance in time. In summary, the Mars rover needs to be designed for autonomous sleep and wake-up. Planetary rovers that carry out dormant wake-up design at home and abroad ...
